Guardium Acid Reflux Control tablets help reduce the amount of acid your stomach makes. They’re used by adults who regularly get symptoms like burning in the chest (heartburn), acid coming up into the throat, or a sour taste in the mouth caused by acid reflux.
Guardium contains esomeprazole, a proton pump inhibitor (PPI). It blocks the action of proton pumps in the stomach lining that produce acid. By lowering stomach acid levels, it helps reduce irritation and discomfort caused by acid travelling back up the food pipe (oesophagus).
Guardium is suitable for adults aged 18 and over. It is not recommended for children or adolescents under 18.

Do not take Guardium with other PPIs or H2 blockers like ranitidine without checking with a GP or pharmacist.
You can take Guardium Acid Reflux Control and products like Gaviscon Advance on the same day, but not at the same time. Guardium works by reducing acid production in the stomach and is taken once daily, usually in the morning. Gaviscon acts as a protective barrier on top of your stomach contents to stop acid from rising, and can be used as needed, especially if you get breakthrough symptoms later in the day. Wait at least 1 hour after taking Guardium tablets before using Gaviscon. Taking them too close together may affect how well Guardium is absorbed.
Take Guardium before a meal, preferably in the morning.
Yes, antacids can be used while taking Guardium if you need fast relief, as Guardium does not work immediately. Avoid using other PPIs or H2 blockers at the same time.
As a precaution, avoid use in pregnancy or while breastfeeding. Speak to your doctor or pharmacist for further advice.
“If you’re having a flare-up of heartburn or acid reflux, Guardium can help settle things quickly. It’s designed for short-term relief and gives your stomach time to calm down while your symptoms ease.”
